Upgrade Xiaomi Gateway 3 firmware for HA 2025 Integration

Hardware
1

I have a Xiaomi Gateway 3 mgl03 with firmware 1.4.6, using AlexxIT’s integration version 2.1.2 on HA 2023.1.1.
After upgrading, the integration stops working properly and requires an update for the integration .

On the GitHub page it states that firmwares from 1.4.6 to 1.4.7 for the Xiaomi Multimode Gateway may work but are UNSUPPORTED.

I believe I can upgrade from version 1.4.6 to versions that apparently work, such as 1.5.0–1.5.4, since I can access my Xiaomi Hub via Telnet.

My question is the following:
At the moment, with HA 2023, everything is working — lights, door sensors, temperature sensors, and even my smart plugs report energy consumption. But I bought a Shelly Button RC 4, which only works properly with the new BTHome versions available in HA 2024 or 2025. That means I need to upgrade to HA 2025.

Has anyone tested the Xiaomi Gateway 3 with firmware versions above 1.5.0 on HA 2025? If so, are you able to receive all sensor data correctly?

If I upgrade the Xiaomi Gateway firmware to 1.5.4, will I be able to downgrade back to 1.4.6 in case the results are not good?

I was able to upgrade the firmware to version 1.5.4 then, upgrade the HA from 2023 to 2025 and finnaly upgrade Alexxit integration Xioami Gateway 3 to the last version. Everything is now working, expect the energy panel. I can reach the power (w) and energy (kWh) in the standard Dashboards, but only after turning on the Sensor statistics on the Xioami Gateway integration configuration that I was able to get the sensors in the energy panel. However, the graph bars don’t move, they are all in 0.
